31. Seismic wave fields are recorded by a seismometer, hydrophone ( in water ), or accelerometer.32. These electronic signals travel much faster than seismic waves . 33. The probe would send information back to the surface by emitting high-frequency seismic waves , Stevenson said. 34. It gives the energy E ( s ) given from earthquakes from seismic waves in ergs. 35. The probe would send information back to the surface by emitting high-frequency seismic waves , Davidson said. 36. Wrong assumptions on the attenuation of seismic waves may introduce errors of a factor of 3. 37. They say the puzzling dual seismic waves are, in fact, a single wave that divided underground. 38. :: Don't forget to read about seismic waves . 39. The quake was likely to have caused a very small seismic wave , or tsunami, Leonard added. 40. Seismic anomalies are identified by mapping variations in wave speed as seismic waves travel through Earth.
